Water still leaking to waste when pump is on filter

[Horanis]

Hello,
I noticed that the water is coming out of waste line when pump is on filter mode. I order a new key assembly (link below) and replaced it but it didn't fix the problem.
Do I need to replace the whole top mount?

Did you lube the o-ring and spider gasket before installing it? If you post pictures of the filter and the problem it may help us find a solution for you.

I didn't lube the gasket because the key assembly cover I bought has built-in gasket. I did lube the o-ring. I will uninstall the key cover assembly again and post some pictures later today.

you might try moving the key a fraction. turn pump off, push handle down as if you are going to change valve position, but just bump it a fraction and reseat the key. that has worked for me in the past when i had that problem.

Update: I removed the key cover and found some dirts on the gasket. I cleaned it and installed it again and now leaking is gone. I did not have to use a lube.
